"This survey of the state of Canadian lakes originated when the International Lake Environment Committee (ILEC) proposed a large data gathering exercise in Canada in the winter of 1988. The National Water Research Institute (NWRI) received support from ILEC to conduct the survey which was undertaken in collaboration with Brock University. The survey was carried out using a comprehensive questionnaire developed by ILEC. It was sent to scientists and water quality managers in government agencies and universities across Canada. The questionnaire focussed on limnology and the impacts of eutrophication, siltation, acidification, and toxic contamination"--Introduction, page 1.
